Scored across 7 tools
Each tool targets a distinct read-only aspect: trace search, full trace retrieval, decision events, alerts, usage, costs, and budget health check. The descriptions clearly separate them even where they overlap (e.g., usage vs. costs are explicitly differentiated).
All tools follow a verb_noun pattern with mostly 'get_' prefixes; query_traces and check_budget deviate slightly but are still predictable. The naming is consistent enough that an agent would not be confused.
Seven tools is well-scoped for a read-only monitoring API. Each tool has a clear, non-redundant purpose, covering search, detail, decisions, alerts, usage, costs, and budget—neither too few nor too many.
For a read-only trace and monitoring surface, the tool set is complete: it covers listing/searching traces, retrieving full traces, filtering decisions, and accessing alerts, usage, costs, and budget status. No obvious read operations are missing for the stated purpose.
